Abstract: The invention relates to a method for setting and operating redundant paths in a quantum communication network, wherein a transmitter implements simultaneous transmission of signals on a working path and protection paths. The signal transmitted on the working path is a primary signal, and the signals transmitted on the protection paths are follow-up signals. In a case that the working path is normal, the transmitter forwards the primary signal on the working path level by level, to implement long distance transmission of a quantum signal. In a case that the working path fails, a proxy working path is selected from the remaining protection paths with the highest priority, and the transmission of information is eventually completed on the proxy working path. It can be prevented that unknown quantum information is damaged and becomes unrecoverable during transmission, thereby greatly improving the security, stability, and reliability of information transmission during quantum communication.
